Description

TECHNICAL FIELD

[0002] With the continuous pursuit of people's quality of life, clothes made of wool and eiderdown are more and more widely used in people's wardrobe, but improper handling methods or means often cause quality problems when caring for such clothes. For example, during the drying process of wool clothes in a drum dryer, due to the influence of complex heat, humidity and mechanical action, wool fabric is prone to dimensional change, which causes wool fabric to felt during drying, and the fabric shrinks and thickens after drying, which makes the fabric feel rough, which greatly affects the style and appearance of the wool fabric.

[0003] When using a drum dryer or a drum washer-dryer to dry clothes, a support is generally placed in the drum to ensure that the clothes do not shrink or reduce shrinkage, and then the clothes are placed on the support for drying. This drying method causes the clothes to be folded, and the air in the drum cannot penetrate the clothes, resulting in only the surface of the clothes being dried, while the inside is damp, requiring the user to constantly reverse the drying operation, which is relatively cumbersome. At the same time, uneven drying of the clothes can cause damage to the clothes and affect the overall drying effect of the clothes. SUMMARY

[0054] In order to make the above objectives, characteristics and advantages of the present application more apparent and comprehensible, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0055] One of the core ideas of the embodiments of the present application is that the existing drying method cannot penetrate the clothes in the drum due to the clothes being folded, so that only the surface of the clothes is dried, the inside is wet, the user needs to continuously reverse the drying operation, the operation is relatively troublesome, and the clothes are not evenly dried, which can easily cause damage to the clothes and affect the overall drying effect of the clothes. Therefore, the embodiments of the present application provide a clothes drying method: controlling a clothes drying device to perform dewatering treatment on clothes, and detecting the water content of the clothes after the dewatering ends; in a case where the water content of the clothes is greater than a first water content threshold, controlling the clothes drying device to perform refrigeration on air in the drum; after the refrigeration ends, controlling the clothes drying device to perform dehumidification on the drum; in a case where the water content of the clothes is less than or equal to the first water content threshold, controlling the clothes drying device to perform heating on the air in the drum until the water content of the clothes is less than or equal to a second water content threshold; in a case where the water content of the clothes is less than or equal to the second water content threshold, stopping the heating on the air in the drum until the clothes are dried. By performing refrigeration on the air in the drum and dehumidification after the refrigeration, the water in this state can be easily exchanged with the air, ensuring the dehumidification effect of the wool in this stage. The water in the clothes is difficult to separate from the fibers of the clothes in a low-temperature state, so the temperature of the clothes during the drying process must be increased, and the clothes are not damaged by high temperature. Finally, the clothes drying device is controlled to stop heating, and the residual heat of the drying is used to make the water vapor move to the air, perform heat and moisture exchange, so that the clothes do not move and do not cause shrinkage.

[0056] Referring to Figure 1 , a step flowchart of a clothes drying method provided by the embodiments of the present application is shown, and the method can specifically include the following steps:

[0057] Step 101, controlling a clothes drying device to perform dewatering treatment on clothes, and detecting the water content of the clothes after the dewatering ends;

[0058] The water content refers to the percentage of water contained in a substance, which is used to describe the water content in clothes. The humidity sensor in the clothes drying device is used to obtain the humidity value of the clothes in real time.

[0059] Wool fibers have a certain directional friction effect, so that wool shrinkage is easily caused when the wool clothes are dried, and the heat generated during the drying process and the water on the wool can exacerbate this phenomenon; according to this principle, the temperature and water content of the wool clothes change with time during the drying process, and the temperature is controlled by the water content of the clothes to reduce the shrinkage of the clothes. The embodiments of the present application are not limited in this regard.

[0060] In the embodiment, when the clothes need to be dried, the clothes after washing are dewatered at a specified rotating speed, and the water content of the clothes is detected to make the clothes reach a certain water content after dewatering, so as to ensure the drying time of the clothes.

[0061] In step 102, when the water content of the clothes is greater than the first water content threshold, the clothes drying apparatus is controlled to cool the air in the drum.

[0062] The first water content threshold refers to the water content range set by the clothes drying apparatus system, and the range is required to be 15% to 30%, preferably 20%. The first water content threshold is set to the system water content range of 15% to 30%, preferably 20%. When the water content of the clothes is greater than this water content range, the water in the clothes is easy to exchange with the air to achieve the best exchange effect. The water content of the clothes monitored by the humidity sensor in the clothes drying apparatus is fed back to the system main control by the device controller for water content judgment.

[0063] At this time, the water content of the clothes is high, and the water in the clothes is easy to exchange with the air. Therefore, the temperature of the air in the drum is cooled, and the fan is turned on to ensure that the clothes with high water content exchange with the air in the drum.

[0064] In the embodiment, the humidity sensor in the clothes drying apparatus obtains the water content of the clothes in real time. When the detected water content of the clothes is greater than the first water content threshold, it indicates that the water content of the clothes is high at this time. The air in the drum is cooled by controlling the clothes drying apparatus to make the water in the clothes exchange with the air.

[0065] In some embodiments, the step 102 includes the following sub-steps:

[0066] In sub-step S11, the heat pump system of the clothes drying apparatus is controlled to start the cooling mode to cool the air in the drum.

[0067] The heat pump system is a high-efficiency and energy-saving heating and cooling technology. It absorbs heat from the environment and transfers it to the space or object that needs to be heated, or removes heat from the space or object that needs to be cooled to the environment. The heat is transferred by using evaporators, condensers and other components.

[0068] The temperature of the air in the drum is reduced by the cooling mode to make the water in the air condense into water droplets, and the water in the clothes is quickly removed. Low-temperature cooling can reduce the thermal damage of the clothes during drying.

[0069] In the present embodiment, the humidity sensor in the laundry drying apparatus acquires the moisture content of the laundry in real time. When the detected moisture content of the laundry is greater than the first moisture content threshold, it indicates that the moisture content in the laundry is high at this time. By controlling the heat pump system of the laundry drying apparatus to start the refrigeration mode, the air in the drum is cooled and refrigerated to a certain temperature (in the range of 10-20℃, preferably 15℃), so that the water in the laundry reaches the optimal temperature for humidity exchange with the air. Reducing the temperature of the air in the drum can accelerate the condensation of water in the air into water droplets, thereby quickly removing the moisture in the laundry and reducing the drying time, thereby saving energy. At the same time, the fan is started to enable efficient humidity exchange between the moisture in the laundry and the air.

[0070] Step 103, after the refrigeration is completed, controlling the laundry drying apparatus to dehumidify the drum;

[0071] After the refrigeration is completed, the air in the drum is humidified, and the humid air in the drum is dehumidified to ensure that the high-humidity air is effectively dehumidified.

[0072] In the present embodiment, after the refrigeration mode is completed, the temperature of the air in the drum is low and the humidity is high. At this time, the moisture in the air has condensed into water droplets, but the laundry and the inner wall of the drum may still be damp. After the refrigeration is completed, the laundry drying apparatus is controlled to dehumidify the drum. The purpose of dehumidification is to reduce the humidity of the air in the drum to an appropriate level to ensure that the laundry is dry. By heating the air in the drum, the moisture evaporates and is discharged from the drum, and external dry air is introduced to discharge the humid air in the drum.

[0073] In some embodiments, the step 103 comprises the following sub-steps:

[0074] Sub-step S12, controlling the heat pump system of the laundry drying apparatus to switch from the refrigeration mode to the dehumidification mode to dehumidify the drum.

[0075] In the present embodiment, after the refrigeration mode is completed, the temperature of the air in the drum is low and the humidity is high. The heat pump system of the laundry drying apparatus is controlled to switch from the refrigeration mode to the dehumidification mode to dehumidify the drum. The data of the humidity sensor is used to determine whether the refrigeration mode is completed. According to the preset program, the working mode of the heat pump system is automatically switched from the refrigeration mode to the dehumidification mode. The sensor monitors the temperature and humidity of the air in the drum in real time to ensure the dehumidification effect.

[0076] Step 104, in the case where the moisture content of the laundry is less than or equal to the first moisture content threshold, controlling the laundry drying apparatus to heat the air in the drum until the moisture content of the laundry is less than or equal to the second moisture content threshold;

[0077] The second moisture content threshold refers to a specific value of the moisture content of the clothes during the clothes drying process, at which the control system stops the heating process to ensure that the clothes reach an appropriate drying degree. The purpose of setting the second moisture content threshold is to avoid over-drying and thus protect the clothes from heat damage. The second moisture content threshold ranges from 0% to 10%, preferably 6%. Setting the second moisture content threshold in the system range of 0% to 10%, preferably 6%, can avoid damage to the clothes caused by high temperature during the drying process and prevent over-drying of the clothes.

[0078] Further, the moisture content of the clothes is obtained. When it is detected that the moisture content of the clothes is less than or equal to the first moisture content threshold (which is required to range from 15% to 30%, preferably 20%), the air cooling and dehumidification in the drum ends, and the next heating stage is entered.

[0079] In this embodiment, when the moisture content of the clothes is less than or equal to the first moisture content threshold, the moisture content of the wool clothes is low at this time, and it is difficult for the moisture in the clothes to exchange with the cold air. To ensure the moisture drying of the wool clothes, the temperature of the air in the drum is monitored in real time to ensure that the temperature is within an appropriate range, and the maximum temperature in the drum is not more than 50℃, preferably 37℃ to 42℃. Controlling the heating temperature in the range of 37℃ to 42℃ can effectively prevent damage to the clothes caused by high-temperature drying. Therefore, when the temperature reaches the maximum temperature, the temperature is not increased any more. The appropriate temperature can accelerate the evaporation of the moisture in the clothes and dry the clothes faster. By controlling the temperature in the range of 37℃ to 42℃, the drying speed can be moderate, and over-slow or over-fast drying can be avoided. The moisture content of the clothes is determined by the sensor data. If the moisture content is less than or equal to the second moisture content threshold, the controller stops the heater and ends the heating process.

[0080] In some embodiments, the step 104 comprises the following sub-steps:

[0081] The sub-step S13 controls the heat pump system of the clothes drying apparatus to switch from the dehumidification mode to the temperature rising mode to heat the air in the drum.

[0082] In this embodiment, the moisture content of the clothes in the drum is monitored in real time by a humidity sensor in the drum. When the moisture content of the clothes is less than or equal to the first moisture content threshold, the heat pump system of the clothes drying apparatus is controlled to switch from the dehumidification mode to the temperature rising mode, and the heating process is started to heat the air in the drum and thus dry the remaining moisture in the clothes. When the detected moisture content of the clothes is less than or equal to the second moisture content threshold, the heat pump system of the clothes drying apparatus ends the temperature rising mode.

[0083] Step 105, in the case where the moisture content of the clothes is less than or equal to the second moisture content threshold, stop heating the air in the drum until the clothes are dried.

[0084] When the moisture content of the clothes is less than or equal to the second moisture content threshold, at this time the moisture content of the clothes surface is very low, and it is difficult for the moisture in the clothes to exchange with the cold air, so in this stage, the heating mode is stopped, and the residual temperature is used to dry the last moisture.

[0085] In this embodiment, whether the moisture content of the clothes is less than or equal to the second moisture content threshold is determined by sensor data, and if it is detected that the moisture content of the clothes is less than or equal to the second moisture content threshold, the heating mode of the heat pump system of the clothes drying equipment is controlled to stop, the heating process is ended, the drying degree of the clothes is monitored in real time, and the clothes are completely dried.

[0086] In some embodiments, the method further comprises:

[0087] In the case where the moisture content of the clothes is greater than the first moisture content threshold, the drum is controlled to operate in the first working mode for a first duration; the first working mode is that the drum continuously rotates and reverses at a first preset ratio.

[0088] The first working mode is that the drum continuously operates in a 1:1 forward and reverse rotation mode to make the clothes run close to the drum wall, that is, the drum continuously rotates forward and reverses for one cycle, and operates in this mode for a certain time.

[0089] The first duration is determined according to the moisture content of the clothes and the setting of the drying program. Generally, the first duration is adjusted according to the type, weight and drying mode of the clothes.

[0090] When the moisture content of the clothes is greater than the first moisture content threshold, it indicates that the moisture content of the clothes is high at this time, and the drum continuously operates in a 1:1 forward and reverse rotation mode to make the clothes run close to the drum wall, and in order to further ensure that the clothes have low shrinkage deformation, the drying temperature at this stage must be reduced, so that the scale structure on the surface of the wool fiber is closed, and the deformation is small when receiving mechanical force.

[0091] In this embodiment, the moisture content of the clothes is detected in real time by the humidity sensor in the drum, and when the moisture content of the clothes is greater than the first moisture content threshold, the first working mode is started, and the heat pump system of the clothes drying equipment is controlled to start cooling and refrigeration, so that the drum continuously rotates, ensures that the clothes are evenly distributed in the drum, and makes the drum operate in a 1:1 forward and reverse rotation mode, which can effectively prevent the clothes from being tangled together and ensure that the clothes and air can effectively exchange moisture.

[0092] In some embodiments, the method further comprises:

[0093] After the refrigeration is completed, the drum is controlled to run for a second duration according to a second operation mode; the second operation mode is that the drum rotates intermittently and reverses according to a second preset ratio, and the ratio of the rotation duration of the drum to the stop duration is within a first preset ratio range.

[0094] The second operation mode is that the drum rotates intermittently according to a 1:1 forward and reverse operation mode to make the clothes tightly adhere to the drum wall, and the ratio of the rotation time to the stop time in each cycle of the intermittent rotation is 3.5% to 7.0%.

[0095] In the embodiment, after the clothes drying apparatus completes the refrigeration in the first operation mode, the drum is controlled to rotate intermittently according to a 1:1 forward and reverse operation mode to make the clothes tightly adhere to the drum wall, and the ratio of the rotation time to the stop time of the drum is 3.5% to 7.0%. The 1:1 forward and reverse operation mode can make the clothes uniformly tumble in the drum, avoid the clothes from being wound together, make the clothes uniformly distributed in the drum, and ensure that the clothes are uniformly heated and stressed. To achieve the most effective dehumidification, the rotation of the clothes should be reduced as much as possible when the clothes are controlled to rotate, and therefore the intermittent rotation and the mode of more stopping and less rotating can achieve the best effect in the dehumidification process. At the same time, the heat pump system is controlled to switch from the refrigeration mode to the dehumidification mode, the running duration of the second operation mode is set according to the type of the clothes and the drying program, and the drum is controlled to run for the second duration according to the second operation mode. This mode is mainly to dehumidify the wet air in the drum, and therefore the rotation of the clothes should be reduced as much as possible when the clothes are controlled to rotate, and therefore the intermittent rotation and the mode of more stopping and less rotating can more effectively dehumidify the wet air in the drum.

[0096] In some embodiments, the method further includes:

[0097] In a case where the water content of the clothes is less than or equal to the first water content threshold, the drum is controlled to run according to a third operation mode until the water content of the clothes is less than or equal to a second water content threshold; the third operation mode is that the drum rotates intermittently and in a single direction, and the ratio of the rotation duration of the drum to the stop duration is within a second preset ratio range.

[0098] The third operation mode is that the clothes rotate intermittently in a single direction to ensure that the clothes can be tumbled within a specified time, which can be intermittent wall-adhesion rotation or intermittent tumbling. The ratio of the rotation time to the stop time in each cycle of the intermittent rotation is less than 1.5%.

[0099] In the present embodiment, the humidity sensor of the laundry drying apparatus detects the moisture content of the laundry in real time, and when it is detected that the moisture content of the laundry is less than or equal to the first moisture content threshold, the drum is controlled to operate in the third operation mode, and the drum is controlled to rotate intermittently in a single direction, and the heat pump system is controlled to start the heating mode. At this stage, the scales on the surface of the laundry will open as the temperature rises, and the moisture content of the laundry at this time is also relatively high. In order to ensure that the laundry is not shrunk by the mechanical force generated by the drum, the operation state of the laundry must be reduced, but at the same time, the laundry cannot be stopped, which will cause poor uniformity of the laundry drying. Therefore, the laundry is controlled to be able to turn over within a specified time, and the ratio of the rotation time and the stationary time in each cycle of the intermittent rotation is less than 1.5%. The intermittent single-direction rotation can make the laundry turn over uniformly in the drum, avoid the laundry from being wound together, and make the laundry run closely to the cylinder wall to ensure that the laundry is uniformly distributed in the drum, and the laundry is uniformly heated and stressed. The intermittent turning over can ensure that the laundry can turn over within a specified time, improve the drying efficiency, and ensure that the laundry is dried without being damaged.

[0100] In some embodiments, the method further comprises:

[0101] In the case where the moisture content of the laundry is less than or equal to the second moisture content threshold, the drum is controlled to be stationary until the laundry is dried.

[0102] This stage is a static operation mode for the laundry, which uses the residual temperature in the drum to dry the last moisture of the laundry.

[0103] In the present embodiment, when it is detected that the moisture content of the laundry is less than or equal to the second moisture content threshold, the laundry has been basically dried, and only a small amount of water vapor is in the laundry. In order to prevent the laundry from shrinking, the drum is controlled to operate in a static mode, and the heat pump system is controlled to stop heating, so that the laundry is stationary in the drum and uses the residual temperature in the drum to make the water vapor thermally move to the air for heat exchange, until the laundry is completely dried to end the process.

[0104] Referring to Figure 2, a logic block diagram of a clothes drying method provided by the embodiment of the present application is shown. When the clothes drying starts, the washed clothes need to be dehydrated according to a specified program. After the dehydration is completed, the water content of the clothes is acquired in real time and it is judged whether the water content of the clothes is greater than a first water content threshold. If yes, the heat pump system is controlled to start the refrigeration mode to cool the air in the drum, and the first working mode is run for a first time length. After the first time length, the heat pump system is controlled to change from the refrigeration mode to the dehumidification mode and the drum is run according to the second working mode for a second time length. When the water content of the clothes is less than or equal to the first water content threshold, the heat pump system of the clothes drying device is controlled to start the heating mode to heat the air in the drum, and the drum is run according to the third working mode. The water content of the clothes is acquired in real time. When the water content of the clothes is greater than or equal to a second water content threshold, the heating process is repeated. When the water content of the clothes is less than the second water content threshold, the heating is stopped and the drum is controlled to be stationary to dry the clothes. Finally, the clothes are judged to be dried, and the drying is completed.

[0105] It should be noted that, for the method embodiments, in order to simply describe, they are all expressed as a series of action combinations, but those skilled in the art should know that the embodiments of the present application are not limited by the action sequence described, because according to the embodiments of the present application, certain steps can be performed in other sequences or simultaneously. Secondly, those skilled in the art should know that the embodiments described in the specification all belong to preferred embodiments, and the actions involved are not necessarily necessary for the embodiments of the present application.

[0106] Referring to Figure 3 , a structural block diagram of a clothes drying device provided by the embodiment of the present application is shown, which can specifically include the following modules:

[0107] The dehydration control module 301 is used for controlling the clothes drying device to dehydrate the clothes, and detecting the water content of the clothes after the dehydration is completed.

[0108] The main principle of the wool clothes drying and shrinkage in the embodiment is that the wool fiber has a certain directional friction effect, and the shrinkage can occur. The heat and the water on the wool in the process of drying the wool can aggravate this phenomenon. According to this principle, the temperature and the water content of the wool clothes change with time in the drying process. The temperature is controlled to reduce the shrinkage of the clothes by the water content of the clothes in the control drying process. The embodiment of the present application is not limited in this regard.

[0109] In the embodiment, when the clothes need to be dried, the dehydration control module 301 dehydrates the washed clothes according to a specified rotating speed, and detects the water content of the clothes, so that the clothes reach a certain water content after dehydration, and the drying time of the clothes is ensured.

[0110] The refrigeration control module 302 is configured to control the clothes drying apparatus to cool the air in the drum when the water content of the clothes is greater than a first water content threshold value.

[0111] In this embodiment, the humidity sensor in the clothes drying apparatus acquires the water content of the clothes in real time. When the detected water content of the clothes is greater than the first water content threshold value, it indicates that the water content of the clothes is high at this time. The refrigeration control module 302 controls the clothes drying apparatus to cool the air in the drum, so that the water in the clothes and the air are exchanged.

[0112] The dehumidification control module 303 is configured to control the clothes drying apparatus to dehumidify the drum after the refrigeration is completed.

[0113] In this embodiment, the dehumidification control module 303 controls the clothes drying apparatus to dehumidify the drum after the refrigeration is completed. At this time, the air in the drum is low in temperature and high in humidity. At this time, the water in the air has condensed into water droplets, but the clothes and the inner wall of the drum may still be damp. After the refrigeration is completed, the clothes drying apparatus is controlled to dehumidify the drum. The purpose of dehumidification is to reduce the humidity of the air in the drum to an appropriate level to ensure that the clothes are dry. The air in the drum is heated to evaporate and discharge the water, external dry air is introduced, and the humid air in the drum is discharged.

[0114] The heating control module 304 is configured to control the clothes drying apparatus to heat the air in the drum when the water content of the clothes is less than or equal to the first water content threshold value, until the water content of the clothes is less than or equal to a second water content threshold value.

[0115] The water content of the clothes is further acquired. When it is detected that the water content of the clothes is less than or equal to the first water content threshold value (the required range is 15% to 30%, and preferably 20%), the cooling and dehumidification of the air in the drum is completed, and the next heating stage is entered.

[0116] In this embodiment, when the water content of the clothes is less than or equal to the first water content threshold value, the water content of the woolen clothes is low at this time, and the water in the clothes is difficult to exchange with the cold air. In order to ensure the water content of the woolen clothes, the heating control module 304 heats the drum environment, monitors the temperature of the air in the drum in real time, and ensures that the temperature is within an appropriate range. The maximum temperature in the drum is not more than 50℃, and preferably 37℃ to 42℃. The sensor data is used to determine whether the water content of the clothes is less than or equal to the second water content threshold value. If the water content is less than or equal to the second water content threshold value, the controller stops the heater, and the heating process is completed.

[0117] The heating stop module 305 is configured to stop heating the air in the drum when the water content of the clothes is less than or equal to the second water content threshold value, until the clothes are dried.

[0118] In the embodiment, the heating stopping module 305 determines whether the water content of the clothes is less than or equal to the second water content threshold value through the sensor data, and if it is detected that the water content of the clothes is less than or equal to the second water content threshold value, controls the heat pump system of the clothes drying apparatus to stop the heating mode, ends the heating process, and monitors the drying degree of the clothes in real time, to ensure that the clothes are completely dried.

[0119] In some embodiments, further comprising:

[0120] The first control module is configured to control the drum to operate in a first operation mode for a first time length when the water content of the clothes is greater than a first water content threshold value, and the first operation mode is that the drum continuously rotates and reverses at a first preset ratio.

[0121] In the embodiment, the first control module detects the water content of the clothes in real time through the humidity sensor in the drum, and starts the first operation mode when the water content of the clothes is greater than the first water content threshold value, while controlling the heat pump system of the clothes drying apparatus to start cooling and refrigeration, so that the drum continuously rotates, to ensure that the clothes are evenly distributed in the drum, and the drum reverses at a ratio of 1:1, which can effectively prevent the clothes from being entangled together and ensure that the clothes and air can effectively exchange moisture.

[0122] In some embodiments, further comprising:

[0123] The second control module is configured to control the drum to operate in a second operation mode for a second time length after the refrigeration ends, and the second operation mode is that the drum intermittently rotates and reverses at a second preset ratio, and the ratio of the rotation time length to the stop time length of the drum is within the first preset ratio range.

[0124] In the embodiment, after the clothes drying apparatus completes the refrigeration in the first operation mode, the second control module controls the drum to operate in a mode of intermittently reversing at a ratio of 1:1, so that the clothes run close to the drum wall, and the ratio of the rotation time of the drum to the stationary time is 3.5% to 7.0%, while controlling the heat pump system to switch from the refrigeration mode to the dehumidification mode, setting the operation time length of the second operation mode according to the type of the clothes and the drying program, and controlling the drum to operate in the second operation mode for the second time length. This mode is mainly to dehumidify the wet air in the drum, so when the clothes rotate, the rotation of the clothes should be reduced as much as possible, and therefore the intermittent rotation and the mode of more stopping and less rotating can more effectively dehumidify the wet air in the drum.

[0125] In some embodiments, further comprising:

[0126] The third control module is configured to control the drum to operate in a third operation mode until the water content of the laundry is less than or equal to a second water content threshold, when the water content of the laundry is less than or equal to the first water content threshold. The third operation mode is that the drum rotates intermittently and in a single direction, and the ratio of the rotation time length to the stop time length of the drum is within a second preset ratio range.

[0127] In the present embodiment, the humidity sensor of the laundry drying apparatus detects the water content of the laundry in real time. When the water content of the laundry is detected to be less than or equal to the first water content threshold, the third control module controls the drum to operate in the third operation mode, controls the drum to rotate intermittently and in a single direction, and controls the heat pump system to start the heating mode. At this stage, the scales on the surface of the laundry open as the temperature rises, and the water content of the laundry is also relatively high at this time. In order to ensure that the laundry is not shrunk by the mechanical force generated by the drum, it is necessary to reduce the operation state of the laundry, but at the same time, the laundry cannot be stopped all the time, which will lead to poor uniformity of the laundry drying. Therefore, the laundry is controlled to be able to turn over within a specified time, and the ratio of the rotation time to the stop time in each cycle of the intermittent rotation is less than 1.5%, so as to ensure that the laundry is dried without being damaged.

[0128] In some embodiments, the laundry drying apparatus further comprises:

[0129] The fourth control module is configured to control the drum to be stationary until the laundry is dried, when the water content of the laundry is less than or equal to the second water content threshold.

[0130] In the present embodiment, when the water content of the laundry is detected to be less than or equal to the second water content threshold, the laundry has been basically dried, and only a small amount of water vapor is in the laundry. In order to prevent the laundry from shrinking, the fourth control module controls the drum to operate in a stationary mode, and controls the heat pump system to stop heating, so that the laundry is stationary in the drum and the remaining heat in the drum is used to make the water vapor move to the air for heat exchange until the laundry is completely dried.

[0131] In some embodiments, the refrigeration control module 302 comprises:

[0132] The refrigeration starting submodule is configured to control the heat pump system of the laundry drying apparatus to start the refrigeration mode to cool the air in the drum.

[0133] In the embodiment, the humidity sensor in the clothes drying apparatus acquires the moisture content of the clothes in real time, and when the detected moisture content of the clothes is greater than a first moisture content threshold, it indicates that the moisture content of the clothes is high at this time, and the refrigeration starting sub-module starts the refrigeration mode of the heat pump system of the clothes drying apparatus to cool the air in the drum, and the air is cooled to a certain temperature (in the range of 10-20℃, preferably 15℃), and the fan is started to make the moisture in the clothes and the air exchange moisture efficiently.

[0134] In some embodiments, the dehumidification control module 303 comprises:

[0135] The first conversion sub-module is configured to control the heat pump system of the clothes drying apparatus to switch from the refrigeration mode to the dehumidification mode to dehumidify the drum.

[0136] In the embodiment, the first conversion sub-module controls the heat pump system of the clothes drying apparatus to switch from the refrigeration mode to the dehumidification mode to dehumidify the drum when the air temperature in the drum is low and the humidity is high after the refrigeration mode ends. The refrigeration mode is determined by the data of the humidity sensor, and the working mode of the heat pump system is automatically switched from the refrigeration mode to the dehumidification mode according to the preset program. The sensor monitors the temperature and humidity of the air in the drum in real time to ensure the dehumidification effect.

[0137] In some embodiments, the heating control module 304 comprises:

[0138] The second conversion sub-module is configured to control the heat pump system of the clothes drying apparatus to switch from the dehumidification mode to the temperature rising mode to heat the air in the drum.

[0139] In the embodiment, the second conversion sub-module monitors the moisture content of the clothes in the drum in real time through the humidity sensor in the drum, and when the moisture content of the clothes is less than or equal to the first moisture content threshold, the heat pump system of the clothes drying apparatus is controlled to switch from the dehumidification mode to the temperature rising mode, and the heating process is started to heat the air in the drum to dry the residual moisture content of the clothes. When the detected moisture content of the clothes is less than or equal to the second moisture content threshold, the heat pump system of the clothes drying apparatus ends the temperature rising mode.
